Western Star Discontinues 57X Model to Focus on Vocational Truck Growth

Key Details Western Star has quietly ended production of its 57X on-highway tractor as parent company Daimler Truck North America (DTNA) narrows its focus on the heavy-duty vocational market. The 57X, which launched in 2022 as a replacement for the 5700XE, came in four cab configurations including day cab and various sleeper options. Dealers were notified of the 2025 retirement, though the decision received limited public communication. Why It Matters DTNA is aggressively pursuing vocational truck market expansion, with the 47X and 49X models exceeding sales expectations. The company aims to boost heavy-duty vocational market share from its current 24% to over 35% by 2030 - a 60% sales increase target. This strategic shift comes as DTNA has completely reorganized manufacturing at its Cleveland plant to prioritize Western Star vocational truck production. Market Position Western Star's 2025 Class 8 U.S. retail sales share climbed to 5.5% from 4.8% in 2024. DTNA leadership emphasized that vocational truck owners demonstrate strong brand loyalty, making this segment a critical growth opportunity. The company has the products and manufacturing capacity to capture significantly more market share in coming years.
